Creep crack growth (CCG) studies on metals and alloys have gained importance and momentum in the recent years. In the present study, the creep crack growth behavior of a directionally solidified (DS) cast nickel-base superalloy has been investigated at 1,033K and the results obtained are reported here. The alloy studied is commonly used for producing turbine blades and vanes for aeroengine applications.
